Equilibrium constant Kp for homogenous systems

• $K_P$


  equilibrium constant used for gaseous equilibria

  calculated from partial pressures for a system at constant temperature
• Partial pressure

  adds up to give total pressure of system

  $\frac{moles}{total\ moles}\times total\ pressure$

  in Pa or atm
• gas equilibrium constant, $K_P$

  
• Kp is only affected by

  temperature

  increases when favours products

  decreases when favours reactants
